Description
Technical field
It is that a kind of good airproof performance, conventional efficient be high, security is good the invention belongs to automatic weapon test equipment technical field
Thorax mouthful smog collecting box.
Background technology
When weapons with pipes is launched, due to unburnt propellant powder with flying out for bullet the divergent contour around thorax mouthful
Into thorax mouthful smog, big I reflection powder burning completeness and the gunpowder capacity usage ratio of thorax mouthful smog.Therefore quantitative measurment
Thorax mouthful smog is significant for the research and improvement of weapon.Due to the uncertain of smog, diffusivity and transient state, can
Had difficulties by, enough collection thorax mouthful smog.The structure of wherein thorax mouthful smog collecting box is collected to smog and plays key effect.
Periodical literature《A kind of new laser smog concentration detection system research》(Liu Feng, Liu Guangyuan, Long Zhengji, Jiang are small
It is flat, Chinese laser, 2014) a kind of laser smog detection method is elaborated, its smog collecting box is actually Smoke Detection chamber, if
There is the entrance and exit of smog, photodetector is installed in parallel in two relative side walls of test chamber.
Above-mentioned smog collecting box has the disadvantage that：
1st, without special muzzle sealing device, it is difficult to ensure sealing well in the case where ensureing that many types of firearms are general
Property；
2nd, detection can only be vented naturally after finishing, and wait the gas of box house just to continue experiment, experiment effect after arranging light
Rate is relatively low；
3rd, without safety device, when the pressure of box house is excessive, it is most likely that trigger security incident.
The content of the invention
It is an object of the invention to provide a kind of thorax mouthful smog collecting box, good airproof performance, conventional efficient are high, security is good.
The technical solution for realizing the object of the invention is：
A kind of thorax mouthful smog collecting box, including casing 1, also including seal assembly 2, exhaust apparatus 3, pressure relief device 4, cause high
Close plate 5 and fixed plate 6；The seal assembly 2 is closed with the front end of casing 1 to be connected, and the dense plates high 5 are compressed by fixed plate 6
The rear end of casing 1 is fixed on, the exhaust apparatus 3 and pressure relief device 4 are fixed on the side of casing 1, and are communicated with box house.
Preferably, the exhaust apparatus 3 is structure identical two, and one is placed in the side lower front of casing 1, another
It is placed in the opposite side rear upper of casing 1.
Preferably, the pressure relief device 4 is structure identical two, is respectively placed in the both sides lower rear of casing 1.
Compared with prior art, its remarkable advantage is the present invention：
1st, good airproof performance：It is provided with the forward end seal component [2] of two-layer sealing structure, it is ensured that can be by the mouth of most of firearms
While portion's (including foresight and muzzle attachment) stretches into box house shooting, additionally it is possible to make firearms firm grip and ensure enough
Sealing, with versatility, sealing；Afterbody uses dense plates high, and bullet can be allowed smoothly to fly out casing, it is to avoid produce ricochet
Deng unsafe condition, and its high compactness and special material, it is ensured that bullet passes through rear shell hole energy rapid desufflation, prevents gas from letting out
Effusion is gone；
2nd, conventional efficient is high：Positioned at the exhaust apparatus of casing left and right sides diagonally opposing corner position, when can greatly shorten exhaust
Between, improve conventional efficient；
3rd, security is good：Safety valve on casing, is that a whole set of smog collecting box increased one insurance, it is ensured that enough peaces
Entirely, for the different gun pressures of pistol, rifle and tommy gun, pressure release threshold value can be adjusted, when meeting various small arms firing well
Smog collect with test.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
